Execute Ability

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true, and the description adds useful scope by saying it 'can run any registered ability,' which signals arbitrary side effects. It does not elaborate on what consequences might occur, but the destructive hint covers the core safety signal and no contradiction exists.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short sentences with no filler. The action is front-loaded and the second sentence clarifies breadth, though it is somewhat generic and could have been replaced by more specific guidance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The output schema reduces the need to describe return values, and the core function is clear. However, for a potentially destructive dynamic execution tool, the description lacks safety context such as validating ability names or using discover-abilities first, leaving an agent to infer safe usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and both parameters have meaningful descriptions. The tool description only restates 'with the provided parameters' and adds no detail about parameter formats, allowed ability names, or how parameters relate to the ability being executed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a clear action ('Execute') and resource ('WordPress ability'), and identifies the tool as the primary execution layer. This distinguishes it from the sibling discovery/info tools, though 'ability' remains somewhat generic and the description does not mention the required ability_name field.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this tool is for running abilities, especially as the counterpart to discover/get-info siblings, but it does not explicitly say when to use it versus alternatives. It also omits guidance such as discovering abilities first to obtain valid ability names.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
